The axis of symmetry for the graph of the function is f(x) = x2 + bx + 10 is x = 6. What is the value of b?

1 answer:

7 0

The question is asking us to find the value of b in the function: f ( x ) = x^2 + b x + 10, if the axis of symmetry is x = 6. This is a quadratic function in a form: f ( x ) = a x^2 + b x + c. The formula for the axis of symmetry is: x = - b / 2 a. So: 6 = - b / 2 a; 6 = - b / 2 ; - b = 6 * 2; - b = 12. Answer: b = - 12.

Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and

Use slope formula to find slope −9−5−/12−8=−14/−20=7/10 7/10 = m = slope
y= mx + b
y= (7/10)x + b
(8,5)
(5) = (7/10)(8) + b
b = -3/5

So.... y=(7/10)x −35

 multiply by 10

10y=7x−6 --> -7x + 10y = -6
--> 7x - 10y = 6
So, if 7x - 10y = 3 a good model?

Hello!

Answer:

$\boxed{14j+10}$

Step-by-step explanation:

Distributive property: →→ a(b+c)=ab+ac

Order of operations stands for:

*Left to right*

Please Excuse My Dear Aunt Sally!

First, you remove parenthesis.

6j+8j+5+5

Then, you add by the numbers from left to right.

6+8=14

14j+5+5

5+5=10

14j+10 is the final answer.

Hope this helps!

Have a nice day! :)
